1. In a programmable logic device, a logic element comprising:

  • a memory;

    a multiplexor having a plurality of control inputs and a plurality of data inputs, the plurality of data inputs being coupled to said memory;

    a storage block coupled to said multiplexor, wherein said storage block stores an output of said multiplexor;

    a first plurality of inputs coupled to said control inputs of said multiplexor, said first plurality of inputs being sufficient in number to uniquely select between each of the plurality of data inputs to said multiplexor, each of said first plurality of inputs being programmably coupled to said storage block;

    a combinatorial output, coupled to said multiplexor; and

    a registered output, coupled to said storage block.
